ELECTRIC GAS-LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 596,236, dated December28, 1897.

Application filed May '7, 1897. Serial No. 635,488. (No model.)

To all whom it may concern.-

7 Be it known that we, ADRIAN LIVINGSTON BOGART, of New York, in thecounty and State of New York, and LE ROY S. XVHITE, of W'aterbury, inthe county of New Haven, in the State of Connecticut, have invented anew and useful Improvement in Electric Gas Lighting and ExtinguishingDevices, of which the following is a specification.

This invention relates to an improvement in electric gas lighting andextinguishing devices in which the energization of the electromagnetwhich raises the armature connected with the main gas-supply valve toopen the valve also opens an auxiliary gassupply valve for feeding gasto an ignitingtube, the mechanism which opens the said valves serving tobreak the electric circuit for producing a spark for primarily ignitingthe gas flowing through the auxiliary igniting-tube, which will in turnignite the gas flowing through the main passage.

A further object is to so construct the device that the supply of gasthrough the auxiliary tube will be shut oh. while the valve forsupplying gas to the burner is held open.

A still further object is to provide a new and improved gas-ignitingdevice which can be readily applied to the well-known Welsbach type ofburners without in any way interfering with the structure of the saidburners or interfering with the arrangement of their mantles within thechimney.

A practical embodiment of our invention is represented in theaccompanying drawings, in which- Figure 1 represents a side view of agasburner of the Welsbach type with our 1g. 2 is an enlarged back Viewof the igniting device and the shell or housing for theelectromagnet-coils, armature, and gas-supply valves. Fig. 3 is avertical central section in the plane of the line 3 3 of Fig. 4.. Fig.at is a top plan view. Fig. 5 is a central section through the shell orcasing, the parts within the same being shown in side elevation; andFig. 6 is a transverse section in the plane of the line 6 6 of Fig. 5.

The shell or housing is denoted by A, and it is provided with a suitabletop plate or cap ing to the source of supply.

A valve B is adapted to open and close the supply of gas through thebore a of the projection a, the said valve being provided with I a stem1), which extends downwardly into the interior of the casing A and isthere provided with an armature b, which armature is fixed rigidly tothe said stem and is of disk form with a portion of the disk cut away.

Two electromagnets are mounted within the casing A in position tooperate the armature b when they are energized. One electromagnetcomprises two coils C C and the other magnet one coil C in the presentinstance. A stationary plate (t is located in the casing A between theelectromagnets C, C, and C and the armature I), through which plate thecores 0 c c of the electromagnets project.

Proceeding to describe the auxiliary gassupply device for feeding gas tothe igniting device, a block D is secured to the top a of the housing orcasing A in the present instance by means of a suitable screw (1, thesaid block D being provided with a gas-conduit cl therein, whichgas-conduit communicates with an upwardly-extended tube (1 which tubeextends upwardly the desired distance toward the burner-tip. The upperportion (1 of the said tube is preferably made of some material whichwill allow of the said portion being bent to direct the flame directlyto the burner. The said upwardly-extended tube is provided with asuitable opening cl, located near the sparking device to be hereinafterdescribed. The gas-conduit 6 extends from the interior of the casing Ato the interior of the block D, the flow of gas therethrough beingcontrolled by a valve E, the downwardly-extended stem 6 thereof passingthrough the said conduit 6 and from thence downwardly through the platea into position to be engaged by the armature b when l armature b,therebyopening'the valves l3 and V E. This raising of the valve E willrock the the same is raised and partially rotated by the energization ofthe electromagnet C C. A suitable spring 6 tends to hold the valve Esnugly against its seat, except when the same is positively opened.

Proceeding to describe the sparking device for igniting the gas in theauxiliary supplytube, a stationary contact-piece F is secured rigidly tothe top a of the casing A, but insulated therefrom, the saidcontact-piece being provided with a laterally-extended pin f, located inclose proximity to the opening d in the auxiliary tube (1 Thiscontact-piece E is electrically connected with the electromagnet C O inany suitable manner.

A rocking contact-piece F is provided with a laterally-extended portionf, which rests upon the top of the block D and extends around theuprising tube (1 The contactpiece E is further provided with alaterallyextended pin f which is held normally in contact with the pin fof the contact-piece F. The laterally-extended portion f of the 0011-tact-piece E extends to a point over the auxiliary valve E, and the saidvalve is provided with an upwardly-extended stem 6 which extends throughthe upper wall of the block D into contact with the forwardly-extendedportion of the wing f, so that when the valve E is raised thecontact-piece F will be rocked and the circuit through the pins f fbroken. The rocking contact-piece F is normally held in contact by meansof a suitable spring f which embraces the tube (1 and bears against thetop of the wing f or" the said rocking piece.

The plate a, within the housing A, is provided with a suitable stop orhook a and the armature b is provided with a suitable hook N, which hookis adapted to engage the stop a when the armature b has been raised andpartially rotated for holding the valve B open until the said armaturehas been rotated in the opposite direction and allowed to drop.

The top a is provided with a pair of binding-posts a to which may besecured the wires running to any suitable electrical actuatingmeanssuch, for instance, as a battery.

The electric circuits are as follows: The circuit for opening the valves13 and E passes from the wire attached to the binding-post a through theelectromagnet-coil C, from thence to the electromagnet-coil C, fromthence to the stationary contact-piece F, from thence to the rockingcontact-piece F, and from thence to the casing A, to the gas-pipe, andto the ground. The electrical circuit for closing the valve B passesthrough the wire attached to the binding-post M, from thence through theelectromagnet C and from thence through the plate a and casingA to thegas-pipe, and from thence to the ground.

In operation when it is desired to light the gas the electromagnet O Ois energized, which energization will raise and partiallyrotate thecontact-piece F and cause a spark to ignite the gas escaping through theopening (1 in the tube (1 The flame thus formed will shoot upwardly andignite the gas escaping through the upper end (1 of the tube (1 Fromthence the flame will shoot upwardly in position to i nite the gasflowin g through the main burnertip. \Vhen the magnet O O isdeenergized, the armature b will fall a short distance until stopped bythe engagement of its hook b with the stop a this downward movement ofthe armature being sufficient to permit the valve E to close, but willretain the valve B open. \Vhen it is desired to extinguish the gas, theelectromagnet C is energized, which energization will rotate thearmature Z) sufficiently to release this hook b from engagement with thestop a. The electromagnet is thus deenergized, thereby permitting thearmature Z) to drop and close the valve 13. This partial rotary movementof the armature Z) is caused by having a portion of the same cutaway, asshown in Fig. 6 in dotted lines, whereby the effect of the magnet C C,when energized, will tend to raise and partially rotate the armature inone direction, and the effect of the energization of the electromagnet Cwill tend to cause the armature to rotate in the other direction.

The tube d may be extended to any desired height, and if it is foundthat the flame from the escape-opening d will not flash to the top ofthe said tube other openings (Z may be formed in the upper portion (Z ofthe tube for leading the said flame upwardly to the top of the tube.

By locating the igniting device entirely out side of the chimney allliability of the mantle within the chimney to become torn or injuredthrough the movement of the contact-pieces is done away with, and alsothe said device may be easily applied to any of the burners now on themarket without changing them in any degree.

In operation when the electromagnet C G is energized the movement of thecircuit through the contact-piece is being constantly made and broken,thereby opening and closing the valve E, whereby a flashing of the flamethrough the auxiliary tube (Z is obtained, which flashing produces abetter and surer result in that the top (1 of the tube need not beplaced so near the burner-tip as where a steady flame is required tolight the main flame.

The igniting-tube (1 if so desired, may be extended up exterior to thechimney and have its upper end located in position to ignite the gasfrom the burner-tip from the top of the chimney. \Vhile we havementioned a single burner in connection with this device, it is evidentthat the said device may be employed to light a plurality of; burners,and it is also evident that the igniting-tube maybe branched or extendedto any desired point.

Vhile we have described this device as particularly well adapted for usewith a VVelsbach type of burner, it is to be understood that the samemay be employed with any burner. It is also evident that slight changesmight be resorted to in the form and arrangement of the several partswithout departing from the spirit and scope of our invention. Hence wedo not wish to limit ourselves strictly to the structure herein setforth; but

What we claim is-- 1. In an electric gas lighting and extinguishingdevice, a burner, a gas-supply-controlling valve provided with a stem,an armature secured to the said stem, an electro magnet for actuatingthe armature to open and close the valve, an igniting-tube, an auxiliarygas-supply-controlling valve therefor, the said auxiliary valve beinglocated in po sition to be engaged and opened by the said armature whenthe electromagnet is energized and a sparking device under the controlof the movement of the auxiliary valve, substantially as set forth.
